"While I favor tough measures to punish and deter aggressive and destabilizing behavior by Iran, North Korea, and Russia, this legislation is significantly flawed," Trump said. "In its haste to pass this legislation, the Congress included a number of clearly unconstitutional provisions."

According to NPR, "Normally, Congress leaves presidents full latitude to waive sanctions if it's in the best interest of the U.S.; this bill, however, specifically takes that ability away from Trump and future presidents when it comes to Russia."

In her comments on the bill during a press briefing on Wednesday, White House press secretary Sarah Huckabee Sanders said, "Congress has encroached on the power of the presidency."

Furthermore, Secretary of State Rex Tillerson recently suggested that such measures impede the efforts to improve relations with Russia.

"The action by the Congress to put these sanctions in place and the way they did, neither the President nor I are very happy about that." Tillerson said. "We were clear that we didn't think it was going to be helpful to our efforts. But that's the decision they made...we'll just work with it."
